will enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification:

The present nvention relates to a further improvement of the water seal of rotary grate gas producers working with high pressure blast such as are described in the.

specification to the U. S. application filed 11th October 1911 Serial N4). 654,156. This improved arrangement of the water seal is intended for those cases when it appears de-- sirable or useful tomaintain the'.ash-pan filled with water. In particular this arrangement is advantageous whenever the producer is working with fuel that yields easily fusible ashes or has the propensity to endothermic working;

654:156 the maintenance of the ash-pan filled with water is only possible whenever the level of thewater in the ash-pan is situated belowv the bottom end of the'shaft. If the water levelrises above the bottom end ofthe shaft the pressure within the producer will force the water above the edge ofthe ash-pan until the former level is attained.

Iniorde r. to obviate the drawbacks connected with similar temporary .overflowingyof the water it is necessary to maintain in the exterior annular chamber the same degree of pressure as in-the. shaft of the gas producer and this is obtained in such a manner that the annular" chamber is connected at some place thereof with the blast admission pipe.

In such a case the pressures on the water levelwithin and outside of the shaft will Specification of Letters Patent. Application filed December 21, 1912. Serial No. 737,974.

remain equal to each other andthe driving out of thewater and an overflowing of the same beyond the edge of the ash-pan can no' longer take place.

-The accompanyingdrawing is a vertical section of the lower part'of the gas producer and shows by way of example a form of execution of the. arrangement according to this invention.

a designatesthe grate, b the rotary ashpan which carries the grate, 0 the producer shaft, dthe sheet iron casing which closes the annular chamber 6 to the outward. The

blast pipe to isconnected with the said annular chamber c'by means of the tube 1' .thatis capable of being closed by the damper s; In consequence of this arrangement the pressure prevailing in the said chamber e will be at 3 the same as that which obtains within the shaft c at :0, whereby the overflowing of the water is rendered impossible; by closing the damper s the former condi tions can be restored again.
